Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Measuring linear or angular speed; Measuring differences of linear or angular speeds > Devices characterised by the use of mechanical means > by making use of a system excited by impact
CPC:
Measuring linear or angular speed; Measuring differences of linear or angular speeds (G01P5/00 - G01P11/00 take precedence; ; counting mechanisms G06M) > Devices characterised by the use of mechanical means > by making use of a system excited by impact
No child classifications to compare. This is a leaf node in both IPC and CPC.
